4 Claims. (c1.111-52) This invention relates to means whereby a feeding mechanism by means of the sprocket planter may be attached to the cultivator beams chain G. of a farm tractor, and the object of the invention My invention consists in connecting the frame is to provide very simple means whereby the rec- B of the planter to the beams It of the tractor 5 tangular frame of a planter may be attached to by means of the rigid metallic posts H which at -5 the cultivator beams of a tractor, these beams their lower ends are pivoted by means of the ordinarily extending downward in pairs below bolts 12 to the frame B and which are at their the tractor, and a further object is to provide upper ends passed through clamping members means of this character which will permit the I3. Each clamping member, as illustrated in easy adjustment of the planter with reference to Figure 4, is split at 13 so as to embrace the post 10 the tractor and will permit the lifting or the or rod II, the split po of the Clamping lowering of the planter at the same time as the bers being adjusted towards each other by means cultivator beams are lifted and by the mecha- Of a belt l4 so that When the belt is tightened,

This is due to the fact that the In t drawing, m designates t two beams of members H are pivotally connected at their lower the tractor. These, at their forward ends, are ends by the bolts t0 the frame 13, 50 that y 35 pivoted to the tractor in a manner well known may be inclined to Vertical P s Shown in and requiring no illustration.

the usual traction wheel F which drives the seed By means of this attachment, however, the plant- 55 er is attached to these self-same beams so that no removal is required.

Furthermore, these beams are controlled as to pressure by springs and these springs, which ordinarily act to resiliently depress the beams, will take care of any inequality of pressure. Therefore, there will be no necessity of providing spring means individual to the planter for depressing the planter. Thus the standard attachment of the tractor is utilized as a frame upon which the planter is mounted, which permits the planter to be placed further forward upon the tractor so that a better view of its operation may be had by the operator, and the standard equipment of the tractor used for raising or lowering the beams l D will be used for raising or lowering the planter.

Furthermore, where planters have been mounted upon tractors, the working depth of the planter cannot be regulated with any nicety whereas where the shanks or members i l are employed, the adjustment as to depth of work of the planter can be very readily made since this adjustment is secured entirely by the clamps l3 and a very fine adjustment can, therefore, be secured.

This attachment will permit either two or four planters to be mounted upon the beams of the tractor and my attachment can be used on any all-purpose tractor for the planting of corn, cotton, etc.

It is to be understood that these shanks or members I l are made of 1 inch steel bars so that it makes them particularly rigid and particularly adapted for Working in hard soil.

What is claimed is:

l. A planter supporting attachment for tractors having cultivator beams, comprising a forward pair of shanks and a rear pair of shanks, each shank at its lower end being perforated for the passage of a bolt whereby it may be attache-:1 to the frame of a planter, the rear shanks at their lower ends being laterally deflected, and clamps mounted upon the shanks, each clamp being adjustable vertically upon its shank and having means whereby it may be held in its adjusted position, each clamp being formed to embrace a beam of the cultivator and be clamped in adjusted position thereon.

2. The combination with cultivator beams and a planter disposed below the beams and having a frame, of a forward pair of shanks and a rearward pair of shanks, each shank at its lower end being apertured, bolts passing through the lower ends of the shanks and into the planter frame, split clamps mounted upon the shanks, bolts ole-sing said split clamps upon the shanks, said bolts when released permitting the adjustments of the clamps upon the shanks, each clamp being forked at one end to embrace a corresponding beam, and a bolt passing through each fork and adapted to clamp the fork upon the beam.

3. A planter supporting attachment for tractors having cultivator beams, including a forward pair of shanks and a rear pair of shanks,

each shank at its lower end being perforated for the passage of a bolt whereby it may be attached to the frame of a planter, and clamps mounted upon the shanks, each clamp being adjustable vertically upon its shank and having means whereby it may be held in its adjusted position, each clamp being formed to embrace a beam of the cultivator and be clamped in adjusted position thereon.

4. A shank for supporting a planter upon a tractor having a cultivator beam, the shank be ing perforated at its lower end whereby it may be bolted to the frame of a planter, a clamp mounted upon the shank, the clamp having a passageway through it for he shank and being split at said passageway, and a bolt passing through the split portion of the clamp whereby the clamp may be tightened upon the shank, the shank being forked at its end opposite said bolt to embrace a beam of the cultivator and having a bolt passing through said forked portion whereby the forked portion may be clamped upon said beam.
